prototype 1

Release of PN 20000004 Rev 00 Parts List with child parts and assemblies for building a small number of prototype units. Assembly includes an earphone, wire for a stubby antenna and preliminary user manual, but no enclosure. Manufacturing process documentation includes a product part breakdown structure diagram, a work instruction for packing beta test units and a work instruction for fabricating PN 20000001 (custom inductor).

prototype 2

Revise electrical schematic to correct connectivity of PCB-type inductor, revise PCB design to correct inductor layout, and generate new PCB CAM files. Correct mechanical dimensions of the PCB, create Master Drawing for the PCB, create assembly drawing and work instruction for circuit board assembly. Update work instruction for custom inductor PN 20000001 for clarity (primarily formatting changes, the rev level was not changed as no changes affected the part itself - fit, form or function).

product release

Restructuring of parts lists for product release, including creation of a new top-level marketing assembly part number. An enclosure with hardware was added, the manual and earphone were moved to the marketing assembly, and the stubby antenna was removed and the user manual was updated.

cost/quality improvements

Circuit board orientation in enclosure was inverted to aid assembly and test (mounted PCA component-side-up in enclosure changed to copper-side-up, allowing direct access to circuit board components and off-board wiring while mounted in the enclosure). Location of holes in the enclosure base and lid were adjusted for the new circuit board orientation, and enclosure artwork modified accordingly. To document the changes, the PCA assembly diagram and work instruction were updated for the tuning capacitor being mounted on the opposite side of the PCB, and the enclosure-level assembly diagram and work instruction were updated for PCA mounting change (orientation and new shorter standoffs).
